QSC AG decides to conduct share buyback of up to 10% of the share capital

Cologne, 11 May 2012. The Management Board of QSC AG (German Securities ID 513700/ISIN DE0005137004) has resolved today to buy back shares via the stock exchange of up to 10% of the share capital, corresponding to up to 13,699,913 shares from 21 May 2012 until about 31 December 2012.

Thereby the Management Board makes use of the authorization of the General Meeting of 20 May 2010 to buy back shares of up to 10% of the share capital until 19 May 2015. The shares that are bought back may be used for any purpose set forth in the authorization resolution of the General Meeting of 20 May 2010. This includes in particular the redemption of the shares, the sale of the shares by cash payment near the stock-exchange-price, holding the shares available as cash for growth and the service of acquisition rights, which were granted to members of the Management Board of QSC AG.

The buyback will be carried out by Joh. Berenberg, Gossler & Co. KG, Hamburg, which will decide about the single buybacks independently and unaffected by QSC AG. The buyback will be carried out according to the requirements of Sec. 14 (2), 20a (3) German Securities Trading Act under consideration of the so-called Safe-Harbor-Rules according to Commission Regulation (EC) No. 2273/2003. The details will be published prior to the beginning of the share buyback.

The purchase price (excluding transaction ancillary costs) must not exceed or fall below more than 5% of the stock-exchange-price of the company's shares, that was determined in the final auction in the XETRA-exchange at the Frankfurt Stock Exchange, during the last five trading-days previous to entering into the obligation. If taking the share's final auction stock-exchange-price in XETRA-exchange on 10 May 2012 as a basis, the maximum buyback volume would correspond to an amount of up to approx. Euro 23.96 million.
